This test can't possibly succeed - as you're printing `x29` etc above, while looking for the string `fp` here?

Also even with #112305 when the code actually does compile, it still won't match this test.

Please make sure that you test compile code contributions, and for test additions, that you actually have tested running them and verified that they succeed. If you did try to run the test, was it executed, or was the `REQUIRES` line not really matched?
